I'm sure there are plenty of other services on BitcoinTalk that scam people—so be careful and don't send large amounts of money; even a deposit isn't a guarantee.
Looks like the scammer is slowly evolving.
1. Launch a likable service in the forum
Something that is privacy oriented and preach against KYC and AML scrutiny
2. Pretend to be looking for honest reviews (sometimes launch a review campaign)
Pretend to also update some changes suggested in the review.
3. Contact one of the marketing guys for a possible signature campaign
Possibly the most trusted ones to increase trust.
4. Deposit some escrow as a way of trying to prove that they are serious about reputation
Something not so high so that they could hit a victim fast.
5. Sponsor contests or games around the forum
6. Pull of an exit scam once the money exceeds what they have invested
7. Repeat the scam with a new service a few days/weeks later.
I used to think few months and years, does it come as fast as days and weeks?
Be it as it may, there are still genuine projects who still use the same template above. So, we are not going to judge them hastily, time is the perfect judge.
